To accurately answer your question, I would need to know what the specific icon looks like. However, based on common icons used in PowerPoint presentations:
- A video clip usually has a film or play button icon.
- An audio clip often has a speaker or sound waveform icon.
- A volume control option typically features a speaker icon with sound waves or a volume slider.
- A mute button is generally represented by a speaker with a cross or slash through it.
If you can provide a description of the icon or clarify which one it resembles, I can help you identify the correct answer.
